Short-Run 25 Gbps Copper Link Between Switches Without Fiber or Transceivers
The Ubiquiti UACC-DAC-SFP28-1M is a 1-meter 25G SFP28 direct attach cable (DAC) for connecting switches, routers, or servers at 25 Gbps over passive copper. Both ends terminate in SFP28 connectors that plug directly into SFP28 or SFP+ slots, so there are no separate transceivers to buy, no fiber to route, and no compatibility questions. One cable, one link.
DACs are the standard choice for short-distance high-speed connections inside a rack or between adjacent racks. The 1-meter length handles most rack-to-rack runs where the two devices are within arm's reach. If you need a shorter run, the 0.5M version keeps the cable even tighter. For longer distances beyond what copper can reach, switch to an SFP28 fiber module instead.
Where the UACC-DAC-SFP28-1M Fits
- Rack-to-rack 25G uplinks between UniFi aggregation switches, Pro Max switches, or any equipment with SFP28 ports within 1 meter of each other
- Server-to-switch connections in a server closet or small data center where 25 Gbps throughput is needed without the cost and complexity of fiber optics
- Stacking or aggregation links between switches in the same cabinet where a passive copper connection is simpler and more reliable than active optical
What the Cable Delivers
- 25 Gbps passive copper: Full SFP28 line rate over a 1-meter twinax cable. No power draw from the cable itself since it is passive, not active.
- SFP28 connectors on both ends: Backward compatible with SFP+ (10G) slots. One cable works for 10G or 25G depending on the port it plugs into.
- No transceivers needed: The connectors are built into the cable. No separate SFP28 modules to purchase, insert, or troubleshoot.
- 1-meter reach: Covers rack-to-rack and within-rack connections. For same-rack only, the 0.5M version keeps cable runs shorter.
